DSZ-500 Electro-hydraulic Butterfly Gate, Coal Mine Large Diameter鄂式 Gate Valve, Arch Discharge Valve

Lip gate valves are suitable for bulk density≤2.5t/m3A variety of ore, coal, coke, slag, chemical products, and other loose materials, widely used for bottom unloading in storage for industries such as building materials, metallurgy, chemicals, and glass.

Structural Features:

  Pleated gate is made of carbon steel welded into shape, structure Operates flexibly and reliably with no jamming issues. Equipped with different transmission devices, it can meet various operational requirements. The electric jaw gate uses an electric push rod with an overload protection device, preventing motor burnout. It can be remotely controlled or programmed, and the reciprocating stroke can be Adjustable positioning with self-locking. The electro-hydraulic jaw gate utilizes electro-hydraulic push rods, featuring full hydraulic transmission, allowing for stepless speed adjustment of both pushing and pulling forces. The pneumatic jaw gate employs pneumatic push rods, which can be remotely controlled through accessory combinations or locally operated.SEFFor manual,DEFFor electricYEFFor electro-hydraulic actuation,QEFPneumatic.

Working Principle:

      The gate valve consists of components such as the main body, sector gate, shaft, gears, sealing pairs, and actuator. A handwheel or actuator moves the lever, causing the gears to rotate the sector gate around the shaft, opening the two sector gates to the sides, allowing the material to fall. Once the receiving device is fully loaded, the actuator drives the lever again to reset the sector gate, closing off the falling material.

Usage Instructions:

l        Please note the medium flow direction marked on the gate body during installation. It is essential to add a sealing gasket when connecting the two flanges, and then tighten the bolts evenly.

l        Please identify the direction of the butterfly valve switch during operation, and ensure the actuator is properly wired.

l        Regularly apply lubricant to all drive parts during operation.
